Trigonometric Values Of Quadrantal Angles

Trigonometric Values Of Quadrantal Angles. If the three basis trig functions (sine, cosine and tangent) are known then the secant, cosecant quandrantal angles are easy to find because they will always have the initial side and the terminal side on an axis. A quadrantal angle is one that is in the standard position and has a measure that is a.

In this lesson we will extend our work with trig functions of angles of rotation to any angle in the unit circle. Use reference angles to evaluate trigonometric functions. The sine, cosine and tangent of the standard angles are given below in the table.

Trigonometric functions of quadrantal angle is depicted in the below figure.

It is necessary therefore to have angles of any size, and to extend to them the meanings of the trigonometric functions. Now we will see how we can find the trig function values of any angle. Find the values (if they are defined) of the six trigonometric functions for the quadrantal angle q = 90° (or q = p 2 ). Trigonometric function values of quadrantal angles.
